A multi-axis thrust vectoring engine nozzle in motion. Thrust vectoring, also known as thrust vector control (TVC), is the ability of an aircraft, rocket or other vehicle to manipulate the direction of the thrust from its engine(s) or motor(s) to control the attitude or angular velocity of the vehicle.
The Three-Bearing Swivel Module has to both support the final hot thrust vectoring nozzle and transmit its thrust loads back to the engine mounts. The "fueldraulic" actuators for the 3BSM use fuel pressurised to 3,500 pounds-force per square inch (24,000 kPa; 250 kgf/cm 2), rather than hydraulic fluid, to reduce weight and complexity. One ...
Thrust vectoring for many liquid rockets is achieved by gimbaling the whole engine. This involves moving the entire combustion chamber and outer engine bell as on the Titan II's twin first-stage motors, or even the entire engine assembly including the related fuel and oxidizer pumps. The Saturn V and the Space Shuttle used gimbaled engines. [1]
Delivering almost 22% more thrust with 40% fewer parts than its F100 predecessor, the F119 allows the F-22 to achieve supercruise speeds of up to Mach 1.8. [1] [2] The F119's nozzles incorporate thrust vectoring that enable them to direct the engine thrust ±20° in the pitch axis to give the F-22 enhanced maneuverability.
The F-15 STOL/MTD tested ways to land and take off from wet, bomb-damaged runways. The aircraft used a combination of reversible engine thrust, jet nozzles that could be deflected by 20 degrees, and canard foreplanes. Pitch vectoring/reversing nozzles and canard foreplanes were fitted to the F-15 in 1988.
The engine thrust structure also enables the stage's RS-25 engines to be gimballed. Each engine is mounted an attachment point at the base of the thrust structure, while its hydraulic thrust vectoring system is installed on top of that same structure.
The F-15 ACTIVE showing its 3D axisymmetric thrust vectoring nozzles on its F100-PW-229s. A variant of the -229 fitted with a 3-dimensional axisymmetric thrust vectoring nozzle, referred by Pratt & Whitney as the Pitch/Yaw Balance Beam Nozzle (P/YBBN), was tested on the F-15 ACTIVE (Advanced Control Technology for Integrated Vehicles) in the ...
It is used in a dual engine mount in the H5-2 second stage of the Long March 5 launch vehicles. Within the mount, each engine can gimbal individually to enable thrust vectoring control. [ 1 ] [ 3 ] As with its predecessor YF-75, the YF-75D can adjust its mixture ratio to optimize propellant consumption.
